T all whom t may concern:

Be it known that I, JONATHAN II, SAM- UELs, a citizen of the UnitedStates, residing at Moline, in the county of Rock Island and State ofIllinois, have invented certain new and useful Improvements in Flows, ofwhich the following is a specification, reference being had to theaccompanying drawings.

My invention relates to plows; and its objects are to provide new andimproved mechanism for operating the rear or caster wheel 0r wheels ofsuch a plow.

My invention relates to the improvement of such plows; also, in sundrydetails hereinafter pointed out.

In the accompanying drawings, Figure lis a side elevation. Fig. 2 is atop or plan View. Fig. 3 is an enlarged detail, being a view of aportion of the standard of the caster-wheel and the mechanism by whichit is operated; Fig. 4 is an enlarged detaihbeing a top or plan view ofthe same parts as those shown in Fig. 3; and Fig. 5 is an enlargeddetail, showing the mechanism by which the seeding devices aredisconnected by the operation of the lever, broken away for convenienceof illustration.

Referring to the drawings, 6 indicates the front or carrying wheels,which are journaled upon a bent axle 7. The axle 7, as is best shown inFig. 2, is a single axle bent four times approximately at right anglesupon itself.

8 indicates the plow-beam, which is pivotally mounted upon the centralportion of the bent axle 7 and is provided with a rearward extension 9.

10 indicates a plow-bottom which may be of any Well-known and approvedform of construction.

11 indicates a seedbox `which is mounted upon suitable supports abovethe plow-beam 8 and which in use is provided with any suitableseed-plates, which, being of the wellknown form and description, are notillustrated or further described. The seedbox 11 discharges into the spout 12 and from thence by means oi a tube 13 into the ground behind asubsoiler 14.

15 indicates covering-wheels, which are mounted, by means of suitablesupports, upon the plow-beam 8 behind the plow-bottom 10.

16 indicates a lever which -is pivotally Specification of LettersPatent.

support from the plow-beam 8 and is pro- 55 vided at its lower end witha mutilated gear 17.

18 indicates a mutilated gear which is secured to the bent axle 7 inregistry and adapted to mesh with the mutilated gear 17. 6o

19 indicates a rack which is engaged by a suitable dog operated by athumb-lever 20 on the hand-lever 16.

21 indicates a spring the forward end of which is connected with theplow-beam near .its forward end and the upper end of which is connectedwith a suitable arm 22 on the bent axle 7. y i

All of the parts above described operate in the well-known and usualmanner, and none 7o of them form in themselves any part of my presentinvention. It is believed that it is not, therefore, necessary todescribe them further herein. It is enough to say that it will beobvious that by the rocking of the lever 16 the bent axle is turned inone direction or the other and the plowshare accordingly raised orlowered, the spring 21 operating to assist in the raising of the plow.

23 indicates rear caster-wheels, which are 8o j ournaled upon an axle24.

25 indicates the caster-wheel standard, which is secured to the axle 24and is provided with a sleeve 26, which is secured to the rear end ofthe extension 9 of the plow- 8 5 beam 8, so that the upright portion 25Lof the caster-wheel standard 25 slides in said sleeve.

27 indicates a rack which is preferably integral with the sleeve 26. 9o

28 indicates a lever-the forward end o1 which is pivoted to theextension 9 of the plow-beam 8, near the rear end thereof. The lever 2Sis provided with a thumb-lever 28a, which is ada ted to engage with therack 27 9 5 and lock the liever 2S in any desired position.

29 indicates a link which is pivotally connected at its lower end to thelever 28 a suitable distance to the rear of the pivotal connection ofsuch lever with the beam extenroo sion 9 and is pivotally connected atits upper end with a clip 30, which is carried near the upper end of thecaster-wheel standard 25 between two castings 31. The castings 31 areprovided with suitable openings 1o 5 through which the upper end of thestandard 25 passes and are secured thereto by pins 32 or in any othersuitable manner. The

castings are provided with forwardly-extending arms 31a, to the forwardend of which is secured a centering-plate 33. The centering-plate 33, asis best shown in Fig. 4, is convex in front and is provided throughoutits length with a vertical slot 34. The centering-plate 33 is of alength from top to bottom which somewhat exceeds the amount of therelative motion of the caster-wheel 23 and extension Q-that is to say,the distance which the straight portion 25L of the standard 25 may beslid in the sleeve 26 when the hand-lever 28 is operated, as hereinafterdescribed.

35 indicates a bracket which is mounted upon the top of the rearextension 9 of the plow-beam 8.

36 indicates a latch which is slidingly mounted in the bracket 35, therear end of which is adapted to engage with the slot 34 of thecentering-plate 33 and is held normally in engagement therewith by aspring 3 7.

38 indicates a rod which is slidingly mounted in suitable supports onthe plow-beam 8 and whose rear end is connected with the forward end ofthe latch 36. The forward end of the rod 38 is connected by chains 39 40with the ends of a cross-bar 4l, which is mounted upon a yoke 42,connected with the clevis 43. The draft is applied to the plow byhitching the horses to the yoke 42.

The operation of the devices last above described is as follows: Vhen itis desired to raise the rear portion of the plow-beam upon thecaster-wheels 23, the outer end of the lever 28 is moved forward, thelever 28 and thumb-lever 28";L being released from the rack 27. Thecaster-wheels bearing upon the ground, it will be readily understoodthat by means of the link connection 29 the rear end of the rearwardextension 9 will be lifted bythis movement into the position, forinstance, shown in dotted lines in Fig. 3, the

latch 36 sliding in the groove 34 in the cen-v tering-plate 33, which,as has been said above, is made of suflicient length to permit thismovement to the full extent of the motion desired without releasing thelatch from the groove. It will of course be understood that by thehand-lever 16 and the lever 28 the plow may be properly adjusted to dothe work required or may be lifted from the ground entirely, as may bedesired. It will also be observedl that by means of the latch 36, whichengages the groove 34, and the centering-plate 33 the caster-wheels 23will be centered-that is, held in line with the plow-beam as long as thelatch lis engaged with the groove and that the plow-beam may be raisedor lowered upon the casterwheels without disturbing this engagement. Aslong as the team is pulling strai ht ahead this engagement will b'e thenorma position of the parts. As soon, however, as the team is turned toone side or the other the crossbar 41 is moved by means of the chains 3940 into whichever side this movement is made and the rod 38 will bepulled forward, disengaging the latch 36 from the groove 34. This leavesthe standard of the caster-wheels 23 free to turn in the sleeve 26, andthe caster-wheels will so turn, assisting in the turning of the plow. Assoon, however, ras the draft is straight forward again with reference tothe plow-beam the caster-wheels will turn so as to be in alinement withthe plow-beam, and the convex side' of the centering-plate 33, bearingupon the springseated latch 36, will force it backward until it comesopposite the groove 34, when the latch will be forced by the spring intothe groove and the caster-wheels centered, so as to be in alinement withthe plow-beam and the draft. It will also be clear from what has beensaid above that as the plate 33 is made of a length somewhat greaterthan the sliding motion of the caster-wheel standard in its support thelatch will always be in position to engage the centering-plate no matterat what height the rear portion of the plow-beam may be fixed upon `thestandard of the caster-wheel.

Referring particularly to Fig. 5, 44 indicates a seed-shaft which isjournaled below the seedbox l1 in suitable supports 45 and 9 which isadapted to drive any seeding mechanism in the box ll in the well-knownand usual manner, and therefore not shown. 46 indicates a clutch memberwhich is pinned or otherwise secured to the shaft 44. 47 indicates asprocket-wheel which is loosely mounted upon the outer end of the4seedshaft 44 and carries upon its hub on the inner side a second clutchmember 48. 50 indicates a rod which is slidingly mounted in the suitablesupports 45 below the seedbox 1l, so' as to slide longitudinally ofitself therein. The rod 5() is provided at its outer end wit-h a ring51, which is adapted to engage the groove 49 of the second clutch member48. 52 indicates a spring which bears at one end upon the support 45 andat the other end upon a head 53, secured tothe rod 50, and which actsnormally to keep the two clutch members 46 and 48 in engagement with oneanother. 54 indicates a cam portion on the other end of the rod 50,which is located in alinement with the lever 16 and is adapted to beengaged by said lever when kthe lever is thrown backward almost to itsextreme limit. Upon the movement of said lever 16 thereupon backward toits extreme limit the bearing of the lever `upon the cam portion 54causes the rod 50 to be slid to the left in Fig. 5 against the action ofthe spring 52 and disengage the two clutch members 46 and 48 from oneanother, as is shown in Fig. 5, the dotted lines in said figureindicating the position of several of the parts normally when not forcedintol the other position by the ICO IOS

backward movement of the lever' 16. 55 indicates a sleeve which ismounted on a horizontal part of the bent axle 7 and engages with the hubof the wheel G, so as to be rotated upon the axle when the wheel 6rotates in the driving forward of the machine. This is of the well-knownconstruction and operates in the usual manner and operates to drivegearing of any approved form and construction (and therefore not shown)and carried within `a gear-case 56. 57 indicates a sprocket-wheel whichis journaled in suitable supports and driven by the gearing (not shown)in the gear-case 56. 5S indicates a sprocket-chain which connects thesprocketwheel 57 and sprocket-Wheel 47.

It will be obvious Afrom the above description that when thelast-described parts are in their normal position the seeding devices inthe seedbox 1l will be operated by the rotation of the seeding-shaft 44to drop seed in the usual and well-known manner behind the plowshare l0.l/Vhen, however, the lever 16 is thrown back, so as to raise theplow-bottom out of the ground, said lever engages the cam 54 and forcesthe clutch members out of engagement with each other, whereupon therotary movement of the shaft 44 of course ceases until the plow is againlowered into position.

That which I claim as my invention, and desire to secure by LettersPatent, is

l. rlhe combination with a plow-beam, a standard journaled at the rearend of said 'plow-beam and movable vertically therein, a

caster-wheel carried by said standard, and a lever adapted to raise andlowei the rear end of said beam on said standard, of acenteringplatecarried bysaid standard, a spring-seated latch adapted to engage saidcenteringplate, and mechanism operated by the draft to disengage saidlatch from said plate when the team is turned to either side7 said platebeing adapted to remain in engagement with said latch regardless of thevarying relative position of said standard and said plowbeam.

2. ',lhe combination with a plow-beam, a standard journaled at the rearend of said plow-beam and movable vertically therein, a 5o caster-wheelcarried by said standard, a level' pivoted on said plow-beam, andconnections between said lever and said standard whereby said standardmay be moved longitudinally of itself in said plow-beam, of a center- 55 ing-plate carried by said standard and of a length equal to thedistance of the movement of said standard in said plow-beam, acentering-slot in said plate, a spring-seated latch normally inengagement with said slot, and o mechanism operated by the draft todisengage said latch from said slot when the team is turned to eitherside.

3. The combination with a plow-beam, a standard journaled at the rearend of said plow-beam and movable vertically therein, a caster-wheelcarried by said standard, a lever pivotally connected with the rear endof said plow-beam, and a link pivotally connected at one end with saidlever and at the other end with the upper end of said standard, of acentering-plate carried by said standard and of a length equal to thedistance of the movement of said standard in said plow-beam, acentering-slot in said plate, a spring-seated latch normally inengagement with said slot, and mechanism operated by the draft todisengage said latch from said slot when the team is turned to eitherside.
